Biography

I am Linfeng Zhao (赵林风), a CS Ph.D. student at Khoury College of Computer Sciences of Northeastern University. I’m advised by Prof. Lawson L.S. Wong and also working with Prof. Robin Walters. During PhD: I am collaborating with and visiting MIT LIS group led by Prof. Leslie Kaelbling and Prof. Tomás Lozano-Pérez. I interned at Meta (2024 summer), Boston Dynamics AI Institute (2023 Spring-Summer, WUD team with Jennifer L. Barry) and earlier at Amazon Science (2021 Summer). During undergraduate: I interned at Microsoft Research Asia (2019) and earlier worked with Prof. Hao Su at UC San Diego (2018-19).

I focus on decision-making in robotics and work on the intersection of machine learning, robotics and artificial intelligence. My current research centers on improving open-world and long-horizon decision-making for mobile-manipulation robots, like Boston Dynamics Spot, which involves planning (in task and motion level) and learning (state/action representations, world models, skill policies). My recent work involves improving scalability, generalizability, and efficiency for robotic decision-making, including utilizing knowledge and capabilities in pre-trained multimodal models and leveraging symmetry and compositional structures.
